A carbon atom is most likely to form what kind of bond (s) with other atoms?
Covalent
The element present in all organic molecules
Carbon
Research indicates that ibuprofen, a drug used to relieve inflammation and pain, is a mixture of two enantiomers; that is molecules that what?
Are mirror images of one another
Which two functional groups are always found in amino acids?
carboxyl and amino
Molecules with which functional groups may form polymers via dehydration reactions?
Either hydroxyl or carboxyl groups
These are polymers
Starch, cellulose, chitin, DNA
How many water molecules of water are needed to completely hydrolyze a polymer that is 11 monomers long?
10
Relationship between dehydration reactions and hydrolysis
Dehydration reactions assemble polymers, and hydrolysis reactions break down polymers
Humans can digest starch but not cellulose because
Humans have enzymes that can hydrolyze the alpha glycosidic linkages of starch but not the beta glycosidic linkages of cellulose
Bonds created during the formation of the primary structure of a protein
Peptide bonds
The tertiary structure of a protein is the
Unique 3D shape of the fully folded polypeptide
Nucleotides
Class of molecules that has a nitrogenous base, a phosphate group, and a pentode sugar.
The cellular process of breaking down large molecules into smaller ones
Catabolism
